Something less important: it just happened to me that a glitch remained unsolved, but when I loaded the location in a different instance, the glitch was solved and I couldn't reproduce the problem anymore.
me 2. (using 32-bit version). Is it possible to have DEM and triangle inequality coloring (and maybe other ones) in the next versions?  |

I know why there may be rare unsolved glitches randomly - it's because of multithreading. I will fix it. The coloring - I don't know what it is  Dragging content - I have too little time at the moment, wave coloring is more fun, I will show you soon  |

BTW, is it possible to lower the priority of the threads that do the computations? While rendering (especially in high resolution), it is almost impossible to do anything else.

It could be done in the program, but you can also change the priority of the process in task-manager... |

I actually get better results changing the program's "affinity" rather than it's "priority" This way if you have, for example, 4 processor cores you can limit it to just 2 of them, or even one. Then change other programs to the other cores, or let them use all. But this way no one program monopolizes the processors and everything can run at a steady pace. I used this when rendering an UltraFractal animation (gave UF 2 cores) and a 3D Animation (gave Carrara 1 core), while exploring with Kalles Fractaller (which also had 1 core). I liked this better because no program ever used much less than it's assigned percent of the processor power while using priority any one of the programs could drop below 5 or 10% Using affinity the usage stayed stable and each program used the most it could within those limits (in my example UF used about 50% and each other used about 25%). Hope that helps  |

I have uploaded a new version of Kalles Fraktaler, now version 2.5 News: * Editable palette waves. Sine waves are applied on the RGB values to create the key colors in the palette. The period values specifies the number of periods in the palette - the higher value the faster wave. * Infinite wave colors. Sine waves are applied on the HSB values to create infinite colors. The period values specifies the period lengths - the higher value the slower wave. * 3 rd degree Mandelbrot. Is set in the "Iterations" dialog - since it affects rendering. Thanks knighty for encouraging and for the Series Approximation formulas. Also Key Frame Movie Maker is updated, now version 1.21, to support Infinite wave coloring. The source code is also synced and available from the main page, http://www.chillheimer.de/kallesfraktaler/ |

Awesome!
It is much faster than previous versions. What kind of magic have you done?

Thank you very much for the update!
Already downloaded, now a quick test-render for the new wave function on color palettes. Testing on the 3-power Mandelbrot. I'll post the result.

wow, what an update!   the wave colouring works really nice! and kind of a whole new set to explore.. awesome work!, kalle! edit: haha, I'm sitting here, excited as a little kid! This is such an improvement! |

Stripes of black added manually with the Merge colors function.  Is it possible to combine the waves with the merge function? Not merging a single color, but merging a wave over every 8th step for example. |

Thanks everyone, and thanks for the beautiful images! Is it possible to combine the waves with the merge function? Not merging a single color, but merging a wave over every 8th step for example.
It would be possible I think. But merging too many waves do not give good result, in my tests the whole image turns toward grey as more waves are added... Awesome!

The glitch finder should be faster but that's all I forgot to mention, that Pauldelbrot's glitch detecting method works also on 3rd degree Mandelbrot perturbation. Super!! |

Super!! It should work generally with perturbation since measuring out of sync will always correlate with amount of rounding errors. |

It should work with any Mandelbrot-type fractal with a critical point at zero. In particular zn + c.
Critical points away* from zero might not be capable of causing this type of glitch, but I don't know if other kinds of glitches or difficulties might arise applying perturbation to such systems.
* Well, far enough away. One with a magnitude smaller than 10-16 could still cause this type.
